WebAug 17, 2021 · A vector \(\pmb{ y}\) in vector space \(V\) (over \(\mathbb{R}\)) is a linear combination of the vectors \(\vec{x}_1\text{,}\) \(\vec{x}_2, \ldots\text{,}\) \(\vec{x}_n\) if there exist scalars \(a_1,a_2,\ldots ,a_n\) in \(\mathbb{R}\) such that \(\vec{y} = a_1\vec{x}_1+ a_2\vec{x}_2+\ldots +a_n\vec{x}_n\)
